Sandy (Shadow Planet)
From Tardis Wiki, the free Doctor Who reference
Sandy was Lindsay Wheeler personal assistant. She didn't like how Lindsey was all concerned with profit. When Lindsey destroyed Shadow Loglan she wanted to help the Seventh Doctor stop what was happening there. She went with Hex to find an escape craft and discovered the Lindsay wanted to leave without anyone else. She was Lindsay's shadow self. She didn't like Lidsay's plan and dragged her into a large hole to stop it. (AUDIO: Shadow Planet)
